Nettet28. mai 2009 · In this study, free vibration analysis of a rotating, tapered Timoshenko beam that undergoes flapwise bending vibration is performed. Derivation of the equations of motion of a rotating, uniform Timoshenko beam was made step by step in a previous work of the authors. NettetIn this study, and values are used to model a beam that tapers linearly in two planes. Since the Young’s modulus, the shear modulus and the material density, are assumed to be constant, the mass per unit length , the flapwise bending rigidity and the shear rigidity vary according to the Eqs. (29a) and (29b).
